Several fastidious lactic acid bacteria require a new growth factor, originally termed the Lactobacillus bulgartcu8 factor (LBF), for growth on synthetic media (Williams, Hoff-Jorgensen, and Snell, 1949; Kitay and Snell, 1950). Highly purified concentrates of this factor contained bound pantothenic acid, a finding that led to the discovery that LBF was apparently identical with the fragment of ...

In the first paper in this series (Davidson, Frazer & Hutchison, 1951) it was emphasized that in experiments on the incorporation of radioactive phosphorus (32p) into the nucleic acids and their derivatives in the cell, it was essential, in order to obtain true specific activities, to separate the nucleotide fractions in a form free from all traces of highly active contaminants. The procedure o...

We present a 60-year record of the stable isotopes of atmospheric carbon monoxide (CO) from firn air samples collected under the framework of the North Greenland Eemian Ice Drilling (NEEM) project. CO concentration, δ13C, and δ18O of CO were measured by gas chromatography/isotope ratio mass spectrometry (gc-IRMS) from trapped gases in the firn. We applied LGGE-GIPSA firn air models (Witrant et ...

BACKGROUND Although all-cause mortality in Sri Lanka decreased significantly from 1950 to 1970, subsequent declines have been more modest with divergent trends by age and sex. This study investigates these trends through cause of death analysis for 1950-2006 in adults aged 15-64 years. METHODS Deaths were obtained from the World Health Organisation (WHO) mortality database for 1950 to 2003, a...

OBJECTIVE AND DESIGN To relate UK national trends since 1950 in smoking, in smoking cessation, and in lung cancer to the contrasting results from two large case-control studies centred around 1950 and 1990. SETTING United Kingdom. PARTICIPANTS Hospital patients under 75 years of age with and without lung cancer in 1950 and 1990, plus, in 1990, a matched sample of the local population: 1465 ...

The knowledge and treatment of cardiology as practiced circa 1950 is discussed as abstracted from authoritative textbooks of that time and other sources. Advances in treatment and diagnostic techniques since 1950 are presented. Dramatic changes in cardiology have come at the expense of bedside cardiology which needs to be balanced with the technology.
